Avian CSI

WARNING: This post includes some graphic photos that some may find disturbing. Viewers beware! 

Migration has slowed down quite a bit, but that doesn't stop Nick and me from going out and enjoying the slightly cooler weather to go birding. Just yesterday we went out in the late morning to a nice little area called the Wellington Environmental Preserve. This is a fairly new area that opened to the public last year, and we haven't had great numbers of birds here, but we have gotten nice variety and some good ducks that we don't find in most of our other birding hot spots.

It was a fairly slow day. We had previously seen lots of limpkins here as there is an abundance of apple snails. You can tell by all of the empty shells that will line the banks and even along the boardwalk bridges. But we had only seen 1 or 2 limpkins this time. Some of the other highlights from this trip were a number of American Kestrels, about 20 Lesser Scaups, and a juvenile Bald Eagle. We also had some nice views of a female Belted Kingfisher.

On our way out, Nick and I decided to go off the path a little to try to find Savannah Sparrows that we thought we had heard on our way in but were unable to locate. We didn't find them, but instead, we found a whole wing laying in the grass. We'll see feathers lying about all the time, but never a whole wing! It was perfectly intact. You could see where the bone had been cleanly snapped off. By the looks of the size and the color of the wing, we determined that it must have been a limpkin.

So that made us think, hmmm, where is the rest of it? We looked a little bit more in the grass, and about 5 feet away we found the rest of the remains. There wasn't a body, but there was the other wing, 2 legs, a bill, and more feathers. We were able to confirm that it was indeed a limpkin, especially because of the bill. Again, viewers beware, but it looks like there was also the bird's throat. (Eww, gross, I know!)

And then a few more feet from this evidence of a kill is what we determined to be the "plucking station," where the predator must have cleaned off the little feathers of the poor limpkin. We determined that it must have been a large bird of prey like a Peregrine Falcon that could have taken this large water bird down and cleaned it so well -- the limbs and bill snapped off so neatly like breaking small twigs off of a larger branch.

There was definitely a mix of emotions -- pity for this poor limpkin, a bit of disgust, but also intriguing wonderment of this evidence left behind of predator versus prey in the avian world.

And to make you feel better, below are some pictures of a viceroy butterfly also taken during our birding adventure. =)

Wellington Environmental Preserve

Yesterday morning, Maureen and I returned to Wellington Environmental Preserve for our second visit to this spacious (365 acre), brand-new public wetland. Just a few weeks ago we made our way up to twitch us some Canvasbacks, which are uncommon visitors to Palm Beach County. We had been able to find the Canvasbacks, but the vastness of the park left us wondering what we were missing.

This time around there were noticeably fewer waterfowl - an ominous sign that we're getting on with Spring, and about to lose our Winter visitors. All that remained of this group were a lone female Northern Shoveler, a male Ring-necked Duck, several Blue-winged Teals, and Florida's very own Mottled Ducks, which won't be going anywhere.

Right out of the car Maureen (who has more of an ear for birdsong than I do) heard an Eastern Meadowlark. Our only other Meadowlarks were during a day-trip to Galveston late last year, making this a state bird for us. It took some effort to locate where the bird was perched because of the distance their song carries. We finally picked it up as a speck across the street and in someone's private property, effectively keeping us from obtaining a better view. Once we started for the trail, though, we heard several others, which sounded like they were always just ahead of us. We were only able to locate one other, but he was pretty lively. Initially, we found him in a tree, before he flew down to the ground, walked across the path and into a clump of tall grasses (and singing the whole time).

One thing about Wellington Environmental Preserve is that they are Limpkins EVERYWHERE! Above all others, this is the bird that you know you're going to find when you come here. Apple snail shells litter the shores, and sometimes you even find yourself crunching a discarded shell underfoot on the boardwalk. There are so many Limpkins, in fact, that even the Limpkins want to see what else is around (see below).

Among the highlights of the day was when we picked a single American Avocet out of a small flock of Black-necked Stilts. It's always a pleasure to pick up a new county bird, as this was for us. Still, it's a shame that we didn't get to see it stick around, since Avocets are among my favorite shorebirds, and we only see them rarely, and usually from a great distance.

The Palm Warblers are all looking fancy in their breeding plumage, which in Florida, means that they're getting ready to leave us any day now. All throughout winter, these common birds are the classic LBJs, and now look at them! It's like watching a caterpillar become a butterfly. I wish them well on their journey back north.

When we arrived at the 6-story observation tower, we felt obligated to trudge our way up, since we had been short on time during our only other visit. It turned out to be well worth the effort. From that vantage, we were able to watch a juvenile Northern Harrier terrorize dozens of Common Moorhens and American Coots. Just a couple of minutes later, a juvenile Snail Kite flew in low from the direction that we'd just seen the Harrier disappear.

From above, a juvenile Harrier and a juvenile Snail Kite can look remarkably similar - both are brown overall, with a broad patch of white toward the base of the tail. Luckily, we were on our toes and weren't taking anything for granted, for which we were rewarded by watching the kite snatch an apple snail out of the water. Easy prey, perhaps, but still, it's pretty awesome to watch a Snail Kite do as Snail Kites do.

Florida very fortunate to have it's very own population of Sandhills with us year-round, albeit not in anything near the numbers seen in the Platte River valley. Early on, we had a group of five fly over while making their bugling calls. This one was just taking a stroll.
